“Faith Without Works is Dead” discusses James 2:8-17. God measures faith by how we act in response to our faith.
“If you really fulfill the royal law according to the Scripture, “YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF,” you do well; but if you show partiality, you commit sin, and are convicted by the law as transgressors. For whoever shall keep the whole law, and yet stumble in one point, he is guilty of all. For He who said, “DO NOT COMMIT ADULTERY,” also said, “DO NOT MURDER.” Now if you do not commit adultery, but you do murder, you have become a transgressor of the law. So speak and so do as those who will be judged by the law of liberty. For judgment is without mercy to the one who has shown no mercy. Mercy triumphs over judgment. What does it profit, my brethren, if someone says he has faith but does not have works? Can faith save him? If a brother or sister is naked and destitute of daily food, and one of you says to them, “Depart in peace, be warmed and filled,” but you do not give them the things which are needed for the body, what does it profit? Thus also faith by itself, if it does not have works, is dead.” (James 2:8-17)
